Twenty bronze sidewalk plaques guide pedestrians on a stroll through queer history in San Francisco’s Castro district. The Rainbow Honor Walk, a growing monument along the streets of San Francisco honoring LGBT pioneers, debuted one year ago. To celebrate the anniversary, Out in the Bay re-airs Eric Jansen’s interview with Rainbow Honor Walk co-founder David Perry at 7pm Thursday.  Or listen right now at the link below. You’ll also hear Steven Short’s feature on “The Queer Past Becomes Present,” an ongoing exhibit at the GLBT History Museum on 18th Street, also in the Castro.  (First aired October 2, 2014; rebroadcast 7pm PDT Oct. 1, 2015, on 91.7fm SF/ kalw.org)
